Gliese 422 b is an unconfirmed exoplanet orbiting the red dwarf Gliese 422 (Innes' star). Gliese 422 b was discovered in 2014. It has a minimum mass of about five times that of Earth.[1]

It is located within the circumstellar habitable zone (HZ) of Gliese 422, which extends from 0.11 to 0.21 astronomical units.[1] Gliese 422 b's semi-major axis is 0.119 astronomical units and its orbital period is 26.161 Earth days.[1]
